In these figures, the right side is the positive side in the X direction, and the left side is the negative side in the X direction. Further, the upper side in these figures is the positive side in the Y direction, and the lower side is the negative side in the Y direction.

In FIG. 5, each sample image GS is an image indicating the character “A”, and a case where the above-mentioned attributes a and b are used as attributes of the image is illustrated. Here, the attributes a and b are examples of the first attribute and the second attribute that are different from each other. Each sample image GS can accept an operation from the user by an instruction by the indicator body 90 or the like. When the operation is performed, the attribute of the sample image GS selected by the operation is set as the attribute of the image GD.

The plurality of sample image GSs exemplified in FIG. 5 include columns a (1), a (2), a (3), a (4), a (5), a (6) and a () arranged in the X direction. 7) and rows b (1), b (2), b (3) and b (4) arranged in the Y direction are arranged side by side in a matrix. In columns a (1), a (2), a (3), a (4), a (5), a (6) and a (7), the types of the above-mentioned attributes a are different from each other. For example, in columns a (1), a (2), a (3), a (4), a (5), a (6) and a (7), the attributes a exemplified in FIG. 4 above are shown. Multiple types of are assigned. This allocation may be set in advance or may be set based on the attribute history information D. On the other hand, in the rows b (1), b (2), b (3) and b (4), the types of the above-mentioned attributes b are different from each other. For example, rows b (1), b (2), b (3), and b (4) are assigned a plurality of types of the attribute b illustrated in FIG. 4 above. This allocation may be set in advance or may be set based on the attribute history information D.

The number of rows and columns of the plurality of sample image GSs constituting the sample image group GSG is not limited to the number exemplified in FIG. Further, the arrangement of the plurality of sample images GS is not limited to the arrangement shown in FIG. For example, in FIG. 5, the intervals of columns a (1), a (2), a (3), a (4), a (5), a (6), and a (7) are not constant, but are constant. Good. Further, the relationship between the attributes of the row and the column may be opposite to the relationship shown in FIG. The extending direction of the row or column may be inclined with respect to the X direction or the Y direction.

The plurality of sample image GS includes a first image GS1 and a second image GS2 which are two sample image GSs in which the settings of the attributes a and b are different from each other. The first image GS1 is any one sample image GS among the plurality of sample image GSs. The second image GS2 is any one sample image GS in which the types of the attributes a and b are different from those of the first image GS1 among the plurality of sample image GSs. In FIG. 5, the sample image GS belonging to the columns a (1) and the row b (4) is referred to as the first image GS1, and the sample image GS belonging to the columns a (2) and the row b (3) is referred to as the second image GS2. Is shown as an example.

Includes 3 image GS3 and 4th image GS4. The third image GS3 is any one sample image GS in which the setting of the attribute a or b is different from that of the first image GS1 and the second image GS2 among the plurality of sample image GSs. In the fourth image GS4, among the plurality of sample image GSs, the setting of the attribute a or b is different from that of the first image GS1 and the second image GS2, and the respective types of the attributes a and b are the third image GS3. Is any one sample image GS that is different. In FIG. 5, the sample image GS belonging to the columns a (2) and the row b (4) is referred to as the third image GS3, and the sample image GS belonging to the columns a (1) and the row b (3) is referred to as the fourth image GS4. Is shown as an example.

In FIG. 5, as described above, the case where each sample image GS is an image indicating the character “A” is illustrated, but the present invention is not limited to this, and each sample image GS is, for example, as shown in FIG. It may be a line drawing or a figure with attribute d exemplified in FIG.

The sample image group GSG may be displayed independently without displaying the image G based on the above-mentioned image information DS, or may be displayed superimposed on the image G. However, when the image GD is superimposed on the image G and displayed, it is preferable that the sample image group GSG is also superimposed on the image G and displayed. In this case, the sample image group GSG can present the user with the ease of viewing the image GD when the image GD is superimposed on the image G.

As shown in FIG. 7, the sample image group GSG may be displayed by superimposing it on a background image GB different from the image G. In this case, since the attributes of the sample image group GSG can be easily seen by the user, it becomes easy to make a judgment when confirming or changing the setting of the sample image group GSG. For example, as shown in FIG. 8, when the sample image group GSG displayed overlaid on the image G is difficult to see, it is useful to use the background image GB. The background image GB is not particularly limited, but is preferably an image that does not affect the visibility of the sample image group GSG as much as possible, and specifically, is preferably a uniform image such as white. Further, the background image GB may be displayed in a timely manner by switching between display and non-display by an operation from the user or the like, or by setting the display period only immediately after the start of display of the sample image group GSG.

The sample image GS of one or more rows or columns may be an image having a different shape from the sample image GS of other rows or columns. In the example shown in FIG. 9, the shape of the sample image GS in one row is different from the shape of the sample image GS in the other row. For example, the attribute of the sample image GS of the one line is set based on the attribute history information D. Then, there is an advantage that the difference between the setting of the attribute of the sample image GS in the one line and the setting of the attribute of the sample image GS in the other line is easy for the user to understand.

FIG. 10 is a flowchart showing an example of the operation of the display device 10 when the drawing mode is executed. When the display device 10 receives an instruction to execute the drawing mode, the control unit 80 first starts the drawing mode in step S110 as shown in FIG. Specifically, in step S110, the control unit 80 displays the toolbar GT as a menu on the display unit 20, and makes it possible to display the image GD based on the detection result of the detection unit 60.

Next, in step S120, the control unit 80 determines whether or not there is an instruction to end the display of the toolbar GT which is a menu. When there is no instruction to end the display of the menu in step S120, the control unit 80 determines in step S130 whether or not the sample function, which is the function related to the sample image group GSG described above, is set. When the sample function is set in step S130, the control unit 80 determines in step S140 whether or not there is an operation related to the attribute of the image GD with respect to the toolbar GT.

When there is an operation related to the attribute in step S140, the control unit 80 causes the display unit 20 to display the above-mentioned sample image group GSG. At this time, the setting of the attribute used for the sample image group GSG is determined according to the type of operation for the toolbar GT. For example, when the operation on the toolbar GT is an operation related to color, the color is set as the first attribute used for the sample image group GSG. In this case, the second attribute used for the sample image group GSG may be any attribute other than color, but is, for example, thickness. Similarly, when the operation for the toolbar GT is an operation related to the line type, the line type is set as the first attribute used for the sample image group GSG. When the operation on the toolbar GT is an operation related to a figure, the figure is set as the first attribute used for the sample image group GSG.

After that, in step S160, the control unit 80 determines whether or not there is an attribute selection by the operation for the sample image group GSG. If no attribute is selected in step S160, the process returns to step S140 described above. On the other hand, when there is an attribute selection in step S160, the control unit 80 determines the attribute related to the selection as an attribute to be used for the image GD in step S170. At this time, the control unit 80 stores the attribute history information D in the storage unit 30 to reflect this determination result.

After that, the control unit 80 shifts to step S180. Further, control is also performed when there is an instruction to end the menu display in the above-mentioned step S120, the sample function is not set in the above-mentioned step S130, or there is no operation related to the attribute in the above-mentioned step S140. The unit 80 shifts to step S180. In step S180, the control unit 80 determines whether or not there is an instruction to end the drawing mode, and if there is no such instruction, the control unit 80 returns to the above-mentioned step S120, while if there is the instruction, the control unit 80 ends.

As described above, the display system 1 or the display device 10 has the display unit 20 for displaying the image G on the screen SC which is the display surface, and the detection unit 60 for detecting the position on the screen SC indicated by the indicator 90. And a control unit 80 for displaying an image GD based on the detection position of the detection unit 60 on the display unit 20. The control unit 80 causes the display unit 20 to display the first image GS1 and the second image GS2 whose first attribute and second attribute settings are different from those of the first image GS1. Then, the control unit 80 determines the setting of the first attribute and the second attribute to be used for the image GD based on the detection position of the detection unit 60 according to the operation on the first image GS1 or the second image GS2.

Further, as a control method of the display device 10, the display unit 20 displays the first image GS1 and the second image GS2 whose first attribute and second attribute settings are different from those of the first image GS1, and the first image GS1 or According to the operation on the second image GS2, the setting of the first attribute and the second attribute used for the image GD based on the detection position of the detection unit 60 is determined.

According to such a display system 1, the display device 10, or a control method thereof, the setting of the first attribute and the second attribute used for the image GD based on the detection position of the detection unit 60 is set for the first image GS1 or the second image GS2. It can be decided by one operation. As a result, the number of operations can be reduced as compared with the case where the number of attributes assigned to the image for the operation is one for each image, so that the operation burden on the user can be reduced. Here, by displaying the first image GS1 and the second image GS2, it is easy to see the image GD due to the difference in the setting of the first attribute and the second attribute without actually changing the setting of the attribute of the image GD. It is possible to present the image to the user at the same time. Through this presentation, the settings of the first attribute and the second attribute used for the image GD are determined, so that the attributes of the image GD can be set according to the user's wishes.

The first attribute or the second attribute used for the first image GS1 and the second image GS2 is preferably a color, thickness or line type, for example, the above-mentioned attributes a, b or c. Since the color, thickness, or line type is suitable for drawing, it is suitable for the attribute used for the image GD. Further, the color, thickness or line type tends to affect the visibility of the image GD and the like. Therefore, when the first attribute or the second attribute is a color, thickness, or line type, there is an advantage that it is easy to adjust the visibility of the image GD.

Further, it is preferable that the first attribute is color and the second attribute is thickness. The color and thickness tend to increase the number of different types such as the visibility of the image GD as compared with other attributes such as the line type. Therefore, when the first attribute is color and the second attribute is thickness, the range of adjustment such as the visibility of the image GD can be increased as compared with the case where other attributes are used. .. As a result, for example, when displaying the image GD overlaid on the image G, it is possible to appropriately set the attributes of the image GD for various aspects of the image G.

Further, it is preferable that the first attribute is a shape and the second attribute is a color, thickness or line type. In this case, the first image GS1 and the second image GS2 can be displayed with different color, thickness, or line type attribute settings according to the shape drawn by the user.

In the present embodiment, the control unit 80 causes the display unit 20 to display the first image GS1 and the second image GS2 on the image G based on the image information DS from the PC 100, which is an example of the external device. When the image GD is displayed overlaid on the image G, the image GD may be difficult to see depending on the mode of the image G. Therefore, displaying the first image GS1 and the second image GS2 overlaid on the image G is useful when displaying the image GD on the image G.

Further, the display device 10 has a storage unit 30 that stores the attribute history information D, which is the history information regarding the attributes of the image GD based on the detection position of the detection unit 60. The control unit 80 determines the setting of the first attribute or the second attribute to be used for the first image GS1 or the second image GS2 based on the attribute history information D. Therefore, the first image GS1 and the second image GS2 can be displayed by using the setting of the attribute that is likely to be used by the user. Therefore, as compared with the case where the attributes of the first image GS1 and the second image GS2 are set without using the attribute history information D, the setting of the attributes used for the first image GS1 and the second image GS2 is changed. Operation can be reduced.

Further, the control unit 80 causes the display unit 20 to display the toolbar GT, which is an operation image capable of accepting operations related to the display of the image GD based on the detection position of the detection unit 60. Then, the control unit 80 causes the display unit 20 to display the first image GS1 and the second image GS2 based on the operation on the toolbar GT, more specifically, the operation on the pen button PEB or the color selection button CCB. Therefore, the first image GS1 and the second image GS2 can be automatically displayed when necessary in accordance with the operation related to the display of the image GD based on the detection position of the detection unit 60. Here, specifically, when necessary, for example, an operation on the pen button PEB or the color selection button CCB is performed to start drawing the image GD, or to change the attribute used for the image GD. It's time.

In the present embodiment, the control unit 80 causes the display unit 20 to display the third image GS3 and the fourth image GS4. Here, the setting of one or both of the first attribute and the second attribute of the third image GS3 is different from that of both the first image GS1 and the second image GS2. The setting of one or both of the first attribute and the second attribute of the fourth image GS4 is different from that of the first image GS1, the second image GS2, and the third image GS3. Then, the control unit 80 determines the setting of the first attribute and the second attribute to be used for the image GD based on the detection position of the detection unit 60 according to the operation on the third image GS3 or the fourth image GS4. According to the above configuration, the number of display modes presented as a sample of the image GD is larger than that in the case where the third image GS3 and the fourth image GS4 are not displayed. It becomes easier to judge.

Here, it is preferable that the setting of the first attribute of the third image GS3 is the same as that of the second image GS2. In this case, by comparing the second image GS2 and the third image GS3, it is easy to evaluate the visibility of the image GD due to the difference in the setting of the second attribute. Similarly, it is preferable that the setting of the first attribute of the fourth image GS4 is the same as that of the first image GS1. In this case, by comparing the first image GS1 and the fourth image GS4, it is easy to evaluate the visibility of the image GD due to the difference in the setting of the second attribute. Further, it is preferable that the setting of the second attribute of the third image GS3 is the same as that of the first image GS1. In this case, by comparing the first image GS1 and the third image SG3, it is easy to evaluate the visibility of the image GD due to the difference in the setting of the first attribute. Further, it is preferable that the setting of the second attribute of the fourth image GS4 is the same as that of the second image GS2. In this case, by comparing the second image GS2 and the fourth image GS4, it is easy to evaluate the visibility of the image GD due to the difference in the setting of the first attribute.

Further, the first image GS1, the second image GS2, the third image GS3, and the fourth image GS4 are arranged side by side on the screen SC. Here, it is preferable that the first image GS1 and the third image GS3 are arranged side by side along the direction in which the second image GS2 and the fourth image GS4 are arranged. In this case, when evaluating the visibility of the image GD due to the difference in the setting of the first attribute, the first image GS1 and the third image GS3 are compared, or the second image GS2 and the fourth image GS4 are compared. Is easy.
